Reactive blue 220 is a synthetic, reactive dye with aldehyde groups. It is used in gene analysis and as a stain in electron microscopy. Reactive blue 220 stains the nucleus of cells purple and the cytoplasm red. The color of the nuclei indicates the presence of active substances such as ATP, NADH, or GTP. This dye has been used to identify bacteria by their ability to produce CO2 from glucose when grown on an acidic nutrient solution with deionized water and sodium carbonate. The optical properties of this dye are dependent on pH level, becoming more red at lower pH levels (acidic).
